STACK CONSTRUCTION FOR STEAM-CARRIAGES.

To aZZ whom it may concern:

Be it known that I, RoLLIN H. WHITE, a

, citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented a certainnew and useful Improvement in Stack Construction for Steam-Carriages, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

The object of the present invention is to provide suitable stack construction for steamcarriages whereby to produce a sufficient draft to promote combustion and whereby the products of combustion and waste heat will be discharged in such manner as not to annoy passengers.

The invention may be summarized as co'n-' sisting of the construction and combinations of parts hereinafter described, and pointed out definitely in the claims.

In the drawings, Figure l is a side view of my invention and so much of a steam-car riage as is necessary for the understanding of the invention. Fig. 2 is a plan view thereof, partly in section; and Fig. 3 is a front end.

view of the draft apparatus on one side of the vehicle.

In steam-carriages the generator is heated usually by an oil-burner, and the generator is covered by a hood or casing from whichthe products of combustion are discharged through suitable flues, usuallycalled the stacks. It is desirable that the-stacks discharge the products of combustion at such points that the passengers will not be annoyed thereby, and it is also necessary that there shall be a sufficient draft through the stack to promote proper combustion at the burner. This problem has heretofore been most satisfactorily solved by'turning the stack downward, so that it discharges beneath the carriage, and by discharging the ex haust-steam into this downturned stack, so as to create therein a forced downdraft. It is not practical, however, to use a downturned stack in a steam-carriage which condenses the exhaust-steam, because there is no way of creating the necessary downdraft. By the construction hereinafter described, and shown in the drawings, the desired results are satisfactorily attained without using the exhaust-steam to create a draft, and it is therefore particularly useful in a steam-carriage having a condenser.

Referring to the parts by letters, A represents the carriage-body, and D the hood or casing which covers the generator B. The burner, which is not shown, is of course located below the generator, and the waste heat and products of combustion risepast said generator into the upper end of said hood. The upper end of the hood D is closed, save for two laterally-extended draft-tubes d d, which extend out-through the sides of the body, where they discharge into the horizontal longitudinally-extended stacks E between the ends of said stacks. The stacks are open at both ends and are suitably close to the body A. As shown, they are supported by stacks might produce a back pressure in the I draft-tubes d, and thereby diminish the normal draft. To prevent this, when the carriage is moving forward I place in each of the horizontal stacks a deflector K, which is located just in front of the draft-tube d and projects from the inner side of the horizontal stack approximately two-thirds of the distance across the same. The opening which remains between the outer edges of the defiector and the outer wall of the horizontal stack should be large enough to produce the necessary draft; but the deflector acts to prevent the air-current entering the front end of the stack from flowing into the draft-tubes d. If a steam-carriage had never to be moved rearward, this deflector might be permanently fixed; but since it is sometimes necessary to drive the carriage backward it isdesirable to ward. The deflector which is not serving the purpose stated is for the time being useless. In the construction shown, therefore, there is provided in each of the horizontal stacks two of these deflectors, which are pivoted on vertical axes near the inner wall of the stack, wherefore they are capable of severally swinging into operative position or of lying substantially flat against the inner wall of the stack. These two swinging deflectors are connected together by a wire N of such length that when one of the deflectors extends as far as maybe across the stack the other one lies flat against the side thereof.

In the operation of the carriage when an air-current is flowing rearward through the stacks, whether such current is due to the forward movement of the carriage or to the wind when the carriage is standing, the air-current entering the front end of each stack will by its action upon these deflectors cause them to' assume the position shown in the drawingsthat is to say, the front deflector will extend across the stack, while the rear deflector will lie flat against the side. If the direction of the air-current in the stacks is reversed, so that it enters the rear end of said stacks, said current will automatically reverse the position of these deflectors, and thus the deflectors will under all conditions which arise automatically take those posit-ions which are necessary for the proper performance of the described functions.

In automobiles it is a practical necessity that mud-guards be provided. The mudguards for the rear wheels are indicated by G in the drawings, and, as shown, they extend down part way in front of the rear wheels, and horizontally backward over the wheels to or beyond the rear end of the carriage-body. These mud-guards are fastened rigidly to the carriage-body. As shown, the front ends are so fastened by the bracketarms 9, while the rear parts are nailed or otherwise fastened to the under side of the overhanging tonneau-seats. The rear ends of the horizontal stacks are extended through and under these mud-guards, and therefore the products of combustion and waste heat as the carriage is moving forward will be discharged beneath these m ud-guards, which then serve the additional purpose of guiding or deflecting these products of combustion, 850., so that they will certainly be delivered from beneath said mud-guards at the extreme rear end of the carriage.

Having described my invention, I claim- 1. In a steam-carriage in combination with a mud-guard, a horizontal longitudinally-extended stack open at both ends and located outside the carriage-body, one end of said stack extending through one of the mudguards, and a draft-tube connected with said stack, substantially as described.

2. In a steam-carriage in combination with a mud-guard, a horizontal longitudinally-extended stack open at both ends and located outside the carriage-body, one end of said stack extending through one of the mudguards, a draft-tube connected with said stack and suitable deflectors within said stack, substantially as described.

3. In a steam carriage in combination wit the mud-guards, two horizontal longitudinally-extended stacks outside of said body and open at both ends, each one having one of its ends extending through its corresponding mud-guard, a draft-tube in connection with each one of said stacks, and deflectors pivoted within said stacks upon the side thereof, adjacent to the draft-tube, substantially as described.

4. In a steam-carriage in combination with the mud-guards, a longitudinally-extended open-ended stack on each side of the carriage adjacent to and below the seat, and having their rear ends extended'through their corresponding mud-guards and also having their forward ends flush with the front of the forward seat, a draft-tube connected with each of said stacks and suitable deflectors pivoted within said stacks to prevent the wind from blowing down said draft-tube, substantially as described.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
